' Be it known that I. LiEzA SZEMEREY, a subject oi the King of Hungary, residing at New York city, in the county and State of New York, have invented a new andL usej ful .Improvement in Rivet Heating and Holding Tools, of which the following is a specification. a y

This invention relates more particularly to a portable magazine tool for heating rivets, feeding the heated rivets to the work as required and holding them while they are being headed in the work.

One of the principal objects of the invention is'to produce a desirable and practical portable or hand tool by which a considerable number of rivets can be heated and kept in readiness for use and which can be readily operated to place the rivets in the rivet holesof the work and 'to holdthem while they are being headed.`

Other objects of the invention are to produce a portable tool of this character having a conveyerfor moving a number of rivets in procession slowly from a magazine through a heating chamber from which they are .discharged in succession, whereby the rivets can be heated to a substantially uniform temperature suitable for riveting as rapidly asthey are required for use; also to provide a pneumatically actuated device l controlled by a valve adapted to be readily operated bythe hand holding the tool for discharging the rivets; also to provide means for enabling the rivet to be held partiallyy protruding from the tool until its end is inserted in the Arivet hole and then completely ejecting the rivet or shoving it into place in the rivet hole; also to construct the tool so that it can be quickly and easily lled with rivets; and

-also to construct the device in other respects hereinafter described and setforth in the claims, whereby it can be readily operated for the intended purpose.

In the accompanying drawings, consisting of three sheets: Figure 1 is a side elevation of a rivet heating and feeding tool embodying the invention. Fig. 2 is a sectional plan view thereof in line 2 2, Fig. 1. Fig. 3 is a longitudinal sectional elevation thereof in line 3-3, Fig. 2. Figs. 4, 5, 6 and 7 are transverse sectional elevations thereof, on

an enlarged scale, in lines 4 4, 5 5, 6 6,

Like reference characters refer to like parts 1n the several figures,

A represents the body ofthe tool which is provided at the rear end with a handle B adapted 'to vbe grasped by the hand for The body olf the tool is hollow and is divided by a longitudinal partition C into a magazine chamber D and a heating chamber E which entends lengthwise of the body at the opposite sides of` the partition.

The magaaine and heating chambers are lilled w1th rivets which are placed on end Fig. 1 0 is an elevaoflthe I.tool showing rivet while being .with their heads lowermost, and to facilitate the loading of the tool and to enable the rivets to be removed therefrom if desired, the magazine and heating chambers `are preferably provided with outer walls d hinged walls or doors may be held closedl by suitable means, such, for instance, as a top plate e which is provided with edge flanges that embrace the upper edges of the hinged walls and is removably secured on the top of the tool body by screws e2. The hinged walls d and e of the magazine and heating chambers have inwardly projecting Hanges or portions at their lower edges forming between them and the partition C slots in the bottoms of the magazine and heating chambers through which the headed ends of the rivets depend, for coperation with a conveyer for moving the rivets from the magazine chamber through the heating chamber for heating the rivets.

A rotary screw coiiveyer F is shown for lthis purpose, which is arranged longitudinally in the body of the tool, below the magazine chamber, and adapted to engage the 'heads of the rivets in this chamber, so that conveyer shaft is connected to a turbine or rotary motor wheel G which 1s located 1n a chamber g in the rear end of the tool and is forwardly in procession through the heating chamber.

- The invention is not restricted to the de-V scribed means for conveying or moving the rivets through the heating chamber, this conveying mechanism simply being selected as onemeans for the purpose, and other means could be usedfor moving the rivets successively through a chamber in which they are heated during their passage through it.

, `I represents a jects inwardly from lshelf or' ledge which prothe side of the body of the tool beneath the heating chamber and by which the rivets are 'supported while passing' through this chamber. The heating chamber has a downwardly curved front portion z' open at its lower end, and the shelf I terminates somewhat in rear of this downturned portion of the heating chamber so thatwhen each rivet clears the front of the shelf I itv drops shank foremost from the' open end of the heating chamber into a horizontal position in a discharge chamber i', .as .shown in Fig. 3, infront-of an ejecting deviceby which itis adapted to be ejectedy through the-,open front end of the discharge Uchamber.

Gras is suppliedfor y the-flames `from a suitable valvecontrolled pipe K whiclLis connected with the jet orifices k bygnassages le and k2 in the rear. end of the bodygand passages k3 and k* extend'- ing longitudinally through 'the partition C., The air discharge passage L for the conveyer driving motor G is preferably conextends longitudinally .in the and 'has a series of orlfices Z2,

-tool in rear of nected by a passage Z, Figs. ,3 and 7, at the rear end of the tool and 'a passage Z which partition C Fig. 3, for supplying air to the heating chamber to support 4combustion and create the necessary draft forwardly through the heating chamber to an exit opening Z3 at the front end of the heating chamber.

M represents the rivet ejecting device, which, in the construction shown, consists of a plunger arranged to move forwardly in a suitable guide chamber in the body of the 'the discharge chamber z" so as to engage the rivet in the discharge chamber and eject the same forwardly therefrom.

This plunger is connected by a rod to a piston m which works in a cylinder m in the lower portion 4of the tool body.- The plunger and piston are retracted and normally held in the inward or rearward position shown in Fig. 3, by asuitable spring m2 surrounding the piston rod. The rear end of the cylinder m is connected by a, passage N to the discharge passage L for the airvfrom the conveyer motor G. The air to the cylinder m for operating theejector plunger is controlled by a suitable Valve O-in the discharge passage L for'the conveyer motor...

-A slide valve is shown having a stem extending rearwardly'through'a guide opening in the handle of the tool, and provided at its outer end with a head p adapted to be engaged by the thumb of the hand grasping the handle for operating the valve. The valve is normally held in its rearward or open `position by a suitable spring 77 so as to maintain an ,open passage for the air from the conveyer motor to the discharge orifices :into the heating chamber E and permit theiair to discharge into the heating chamber to give the necessary draft for the gasv flames, andthe air passing to the ejector cylinder will not have sufiicie'nt pressure to operate the ejector plunger. When, however, the valve is closed by pressing it inwardly the air pressure will be,increased sufficiently in the passage N and the ejectorq cylinder to move the ejector plunger forwardly for shoving the rivet in front of the plunger out of the discharge opening 2.

Means are preferably` provided for enabling the rivet to be arrested and held tem porarily with its front end protruding from the discharge opening, so that the end of the rivet can be inserted into the hole in the work beforethe rivet is completely ejected from the tool. The means shown for this purpose consists ofa spring latch Q, Figs. 3, 8 and 9, mounted on the body and adapted- -to engage a shoulder q on the ejector plunger to arrest .the plunger when the latter has projected the rivet partially out of vthe discharge opening, and pivoted bottom R for the discharge chamber which liswpressed inwardly by a suitable spring 1 so as to clamp and retain the rivet in thel discharge chamber with its front end protruding therefrom. S` represents a handle or hand grip which embraces and is slidably mounted on the underside of the front portion of the tool in a convenient position to lbe grasped by. the lhand for sup# porting the front end of the tool. ThishandleV is provided with a lug s havingan inclined face adapted, by sliding the handle S rearwardly, to engage a coperating inclined face on the ejector latch Q for retracting the latch to release the plunger. After the protruding end ofthe rivet has been inserted in the hole in the work, the

handle Sis slid rearwardly and the latch Q retracted, which allows the air pressure to move the ejector plunger to the limit of its forward movement for completely ejecting the rivet. The handle S is preferably provided with a covering sv 'of insulating ma? terial suitable for protecting the hand from the heat of the heating chamber.

After-the rivethas been placed in the hole in the Work, as explained, the nose T of the tool is :placed against the head of the rivet,

as shown vin Fig. 10, to hold the rivet while A the other end is being headed. A socket is formed in the nose 'l to receive the headof the rivet. a l It is not intended in this application to limit the invention to the described construcvtion of the tool andthe particular devices 'use is new and that it is Within the scope of the invention to `employ different instrumentalities for securing these results.
